From: Physiological and transcriptomic analyses to reveal underlying phenolic acid action in consecutive monoculture problem of Polygonatum odoratum

Rhizosphere soil sample PPO (mg/d/g) CAT (μmol/d/g) UE (μg/d/g) ACP (μmol/d/g) SC (mg/d/g)
FC 49.269 ± 0.438 17.867 ± 1.022 392.069 ± 32.173a 22.871 ± 0.830 34.800 ± 0.188a
CC 47.727 ± 0.688 17.284 ± 1.026 298.174 ± 14.843 22.004 ± 0.321 20.801 ± 0.177
  1. Note: values were expressed as mean ± standard error, and a was marked for the significant difference within the same column with the T-Student’s method (P < 0.05, n = 3). FC stands for first cropping, and CC stands for continuous cropping. PPO stands for polyphenol oxidase, CAT stands for catalase, UE stands for urease, ACP stands for acid phosphatase, and SC stands for sucrase
